Abstract
The invention is directed to a liquid crystal display and assembly without a contact hole in the reflective layer. By eliminating the contact hole, the overall reflectance of the apparatus is increased. In order to prevent light leakage and afterimage, the invention includes an interface electrode that is strategically positioned over where light leakage occurs. An exemplary display apparatus includes a first substrate having a reflective region and a transmissive region including a transparent electrode, a second substrate including a transparent common electrode, a liquid crystal layer located between the first substrate and the second substrate, and a thin film transistor. The tin film transistor includes a gate electrode, a source electrode, and a drain electrode, and the gate electrode is located in the reflective region. Either the source electrode orthe drain electrode contacts the transparent electrode between the reflective region and the transmissive region.
